Companion planting spacing of different plants

by a fresh gardener

Dear fellow gardeners, I'm trying to find out how far away should I plant non-compatible plants to avoid their harmful vicinity? Or how close should I plant companion plants to make them enjoy their company? I would greatly appreciate any information.
Thank you

I don't know that answer, but I try to keep them ten or more feet just in case.

Here is reverse question.

I have some different varieties of peppers in my garden and my mildly hot pablano peppers were planted next to my banana peppers. So when my wife went to chop a banana pepper up for her omlet it was very hot. I tested that same pepper a few daya later when I thought of it. WOW ! It was hot, another spot from it was lesser so. I planted these same seeds last season and were fine. Must have gotten cross pollenated. So I wonder how far away I should have keep the cool from the hot?
or is it a matter of education with the bees and wasps? Ha!

Companion planting spacing of plants
by: ~ Megan ~

The recognised distance to stop cross-pollination of most plants is 1.6km (1 mile). This would probably not stop every bee, but most winds.

As far as companion planting to avoid plants arguing with each other, it depends what the argument is about! Let's just say in general it's best to plant these warring parties at opposite ends of the garden. But sometimes it's just a matter of not planting in adjacent rows.
Here are examples:
Some plants hog certain nutrients and so can cause nearby plants with the same requirement to suffer.
Some plants have an aggressive root system which can interfere with plants with fine delicate roots.
Some plants give off aromas which attract pests, or conversely repel beneficial bugs needed by another plant variety.
Some plants harbor certain fungus' which don't worry them too much but can explode onto nearby plants of a different variety and kill say, your tomatoes.

For beneficial companion planting, usually the closer the better. Peas provide nitrogen for potatoes for example; flowering herbs attract bees to pollinate your zucchinis; mint can repel aphids; garlic and chives mask the scents that other plants give off that would normally attract certain pests.

Thank a lot for Megan for a good direction of thinking about the question. When you got it it looks so obviuosly.

Companion Planting Space
by: Pat Waters

A very interesting question. I wondered the same a few years ago and found two books that are excellent;
Carrots Love Tomatoes (ISBN 987-1-58017-027-7)
Roses Love Garlic (ISBN 978-1-58017-028-4)
both by Louise Riotte.
If you can find them it's money well worth spent.

Show me one agricultural or horticultural scientific research study; vetted, verified, and peer reviewed, that substantuates any of this "companion planting" nonsense.

Plant your garden. Enjoy the fruits of your labor.

Why do people want to take something so simple and make it so witchcraft complicated?

Companion planting proof
by: Anonymous

Simple? Excuse me, but there's nothing simple about growing plants.. the soil, sun, winds, nutrient requirements, spacing, watering and on and on.
Don't try and tell me that some plants hate being shaded by another plant - they love it if they are say, lettuces. Some plants like lotsa water and some not. Some need more nitrogen than others. It's obvious!

Lack of scientific, peer review etc evidence does NOT mean it's not true, it means that nobody has funded such a study, it does not mean we, who have observational proof time and again, are witches. Ha, may the rotten turnip spell be upon you!

Mystical companion planting or not
by: Stacie

Hello to Nonsense,
You're a bit of a sad sack... fancy not believing even one tiny scrap of evidence. You're going a bit too far, gardening is so much about what works for some and not others. Just like our diets, some things work for some and not for others, because like our gardens, soil, climate etc, our bodies are different. Nothing mystical about that! I bet you were read fairy stories to as a child, and maybe you even read or watch science fiction now. Well these stories often contain a hidden message or moral, so they are not necessarily nonsense. And I say, 'may a herd of wild unicorns ridden by witches trample your garden the next moonlit night.'

Companion planting

Hi, I Garden in zone 2b in 10ft x 4ft x 2ft raised beds.
I plant half a bed in tomatoes and the other half carrots for example and they both grow like crazy.I do this with other plants and sometimes plant them straight down the middle of the beds. It depends on height, shade and each plant's nutritional needs.
Its very important to rotate crops too to prevent disease.
Hope this helps someone. :)

Plant spacing garlic and peas
by: Judy

I was hoping to read something about how far I need to plant garlic from Beans and peas. does any body know this answer?
My garden is only 3.6 meters wide and 6 meters long.
Thank you to anybody who can give me an answer on this.

beans and garlic
by: Euward

all onions, leeks and garlic type plants are recommened to not be planted near beans and peas. It's hard to find out exactly why but maybe because of the nitrogen fixing qualities of peas and beans. I would plant them as far away as you can and observe. Of course you could experiment and plant some garlic close to some beans and see if they grow worse or better than if they are as far away as possible.

Proof Jena Experment Germany they have been planting many different species to see which mix and match. Wondering about good speakers on subject for farm group No-till-Texas

Companion Planting With Seed
by: Mykol

This year I decided to companion plant. I have ample space and have experimented with alternating Corn, Pole Bean, Sunflower, Squash,(C,PB,SF), Melon, (C,PB, SF) Cucumner,(C,PB,SF)...etc.

For one row I space each seed about 3 inches apart. The second row I spaced the seed about 6 inches apart.

Each row I divided into three sections, and the middle section I used Okra instead of Corn (and planted Eggplant in place of Cucumber, and Pumpkin in place of Melon).

Of course, each section has a different variety of Corn/Okra, Cucumber, Squash, etc (I like variety). I may substitute Cantaloupe for the watermelon on my next row.

In a few days I will be making a third row and spacing my seed about 12 inches apart. So, if I remember to return, I will update and let the OP and others know the success/failure of each row.

Mykol, please keep us updated with your plantings, what you are doing is very interesting!

dates on comments
by: Margo

I like to read what others are doing in the garden, but with no dates, I could be reading something from 5 years ago, esp. when someone says they will update us on an experiment.

you say its not backed by science, yet the concept of companion planting comes from looking at evolution and how plants evolve in different ways and how they can work together.

Sure what works for you works for you. But then why do you feel the need to come to others and attack them for doing what works for them?

what's sad is how bitter you are.

Beans near garlic
by: Mike

I also would like to know what a safe distance is to plant beans from garlic. Telling someone to experiment is a stupid answer, as we'll lose a growing season and a harvest. I have always had good pole bean harvests, but with chives and scallions 5 feet away the beans are not doing well. The scallions & chives are fine. Garlic being similar but stronger may wreak more havoc on the bean crop. If anyone has any real data on this please post. It's time to plant the garlic but the space is limited.

Watch out for the sunflowers in that mix--they are allelopathic, that is, they give off toxins (terpenes and various phenolic compounds) that impede the growth of other plants.

Scientific research
by: Anonymous

I just went to google scholar, typed in "companion planting", and found numerous studies on companion planting.

A person who says, "show me the science", when they obviously have the tools to find it for themselves isn’t interested in science.

Universities have departments dedicated to agriculture where they teach companion planting. Types of companion planting includes wind breaks and trap crops. The purpose is to create an ecosystem.

I planted green bell peppers and strawberries within 1 foot of each other last year and both did great. I'm not going to worry too much about it
